To all whom z'tmag/ concern.' y

Beit known that I,- l/VILLIAM E. Gruner,

a citizen of the United States, residing at"` Bow, in the county ofSkagit and State of Washington', have inventedcertain new and usefulimprovements in Gates, cf which the `following is a specification.

particularly to an improved gate forproviding an obstruction to gatewayswhere-` by cattle will be prevented from passing through the-gateway,while the construction of the gate will permit automobiles and similarvehicles to pass through the gate- This invention relates to gates andmore vehicle to open the gate.` e r n One of the objects of theinventionis to' complementary gate memmaticallyl openV and closeV whenan automobile passes through the gateway.

r Afurther object of this invention is the provision of a gate whichconsists of comparatively struction, withstand few parts and is simplein conbut durable and well adapted to the rough usage to which devicesof this character are ordinarily subjected.

For a full' description of n the invention and theadvantages and meritsthereof, Areference is to be had to the tion and the accompanyingdrawings, where.- `in is illustrated the Figure 1 is a longitudinalvertical section through the gate constructed in accordance with myinvention. n Fig. 2 is a vertical transverse section.

Referring to the drawing, wherein is illustrated the preferred form ofmy invention, and in which like numeralsof `reference indicatecorresponding parts throughout the several views, the gateposts land 2are spaced apart the requiredmdistance to form the desired width ofgateway and these gate posts support the fence boards 3 in the usualmanner. i

Between the gate posts, I have provided a frame which 1s sunk partiallyinto the ground and the same consists of the side stringersi and 5 and acentral Stringer 6. The ends of these stringers are fastened to the endcross-pieces 7, the latter being sunk into the ground and attached tothe lower edges 0f the Supports aslearly Shown by leach endof the trame,`posed tread piece 10. i the upper edgesot' the stringere is a plu- 11,'the same having `the tread boards be presently described. way withoutthe` necessity'of stopping the vhinges 12, while `edges of which to thebeveled vdotted lines in Fig.` 1. following descrip wardly, the slats16v lit Vthetread boards1l,ftln1s providing a com-` preferred form ot my.y invention, in which; l

Each gatemember consists of the side beams 15 towhichis connected the ends of a plurality of slats `16, the longitudinalarecut at an angle opposite edges of the tread boards 11 and thewidth ofthe slats? is substantially equal `to the space between the tread boardsas clearlyshown by Fig.` 1 of the drawing. The outer ends of the beams15 are attached to the leavesof the hingesl 12 so that the complementarygate members are free `to swing upwardly to the positions shown by-llVhen swung downin the space between the purpose of which willparatively smooth surface over which the automobile may `pass whendriving through `One ofthe side beams l5 of the gate member 14 carriesan arm 17 which extends beyond the end of the beam and overlaps theproximate. end of the adjacent beamon the gate member 13 when the twogate members are closed. The other gate member 13 has the beam l5 on theopposite side provided with a similar arm 18 which i projects in theopposite direction from the adjacent beamofthe gate `member 14C. These,19 .over which is passed a cable 2Q. in-

ner end ofeach cable is iiXed to the loop 2l, the terminals of whichareV fixed to the -proXi- Y Y postsand a frame arranged between the gatemate ends of the complementary gate members at each side thereof. Theopposite end of each cable 20 carries a weight 22 acting to maintain thecomplementary gate menu beisin raisedpositonv for Closing the gate# wayso that cattle will be prevented froing passing through the gateway.

It will be'obvious that it is merely necessaryto drive the vehicle'overthe edgeof the vtread piece l0, according yt the side 'of' v'the gateapproached by the vehicle." When the front wheels contact with the gatememvis copiesnf this' patent may be obtained for bei', thesamewill beforced downwardly f andthe weights will be lifted, while the gate ofjthe other gate member will cause it toV also'di'op, so that when thevehicle reaches the center of the gateway both gate mem-- bers 'will bein a position to permit the ve hicleV to pass through the gatewayv Thearms 174, and 18 will cause positive action on either gate ineniberintheevent the same should not drop from their own weight when theothergate member is forcedV down.

For permanently fixing vthe `gate in open position, so that cattle maybe permitted to pass through thegateway when desired, I have 4providedapin 23driven intothecenter fof the central support 6 atthe exact centerof the gateway. Y'The pin' projects above th'estringer and carries arotatable latch 24 which may be engaged with the outer surface ofthevproximate 'slats at the end of eachgate member forthe purpose of holdingfthe gate members inV open` position against the tendency of theweights to hold necessary toV give the latch a; quarter turn and theweights will `force the gate `members to closed; position;
